SPECIFICATION forming part of Letters Patent No. 226,456, dated April 13, 1880. Application filed December 6, 1879.

To all whom it may concern:

Be it known that 1, WILLIAM PATTERSON, of Cleveland, in the county of Onyahoga and State of Ohio, have invented certain new and useful Improvements in Paper Bags; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to paper bags; and it consists in the pattern and manner of folding said pattern, substantially in the manner hereinafter set forth.

In the drawings, Figure 1 represents the pattern of my bag. Fig. 2 represents a modified form of said pattern.

In each of the above figures the dotted lines are intended to represent the folds or creases that appear in the developed bag.

Fig. 3 is a plan view of a bag-blank as it is cut from the continuous tube. Fig. 4 is a view, in'jsideQelevation, of the bag-blank shown in Fig. 3. Fig. 5 is a plan view of the first fold; Fig. 6, a view, in side elevation, of the fold shown inf Fig. 5; Fig. .7, a plan View of the second fold; Fig. 8, a view, in side elevation, of the fold shown in Fig. 7 Fig. 9, a view of the third or final fold; Fig. 10, a view, in side elevation, of the fold shown in Fig. 9 Fig. 11, a view of the bottom of a finished bag as it appears open for holding its contents.

In the above figures the dotted surfaces are intended to indicate the paste and to show where itlis applied.

In man nfacturin gm y bags I prefer to out the blanks from a continuous tube formed from a web or ribbon of paper in the usual well-known manner practiced inlipaper-bag manufacture. This web or strip of paper is formed into a contin nous tube having side creases, as shown in Fig. 12 of the drawings, which illustrates a bag-body in transverse section, showing the lateral folds just mentioned.

The first operation consists in separating the blank from the continuous tube, and this blank is illustrated in Fig. 4 of the drawings. The next step consists in forming the first of the bottom folds, which is clearly illustrated in Fig. 5 of the drawings. This fold consists in bringing back upon the seamless side of the bag-body the shorter lip A. The sections B B of the edge of the pattern, by thus drawing back the lip A, are changed from a position at right angles to the length of the bag-body to a diagonal position whose line of direction is between forty and fifty degrees to the line of the length of the bag-body, substantially as illustrated in Fig. 5 of the drawings. When pressed down by rollers or by any suitable means the first fold is completed.

The manner of forming the second of the bottom folds consists in folding upon itself the lower end of the blank, as shown in Fig. 7 of the drawings, and this fold is also fixed by rollers or any suitable pressure.

The third or final fold now remains to be made, and it is formed by tnrnin g back toward the bottom of the bag-body the shorter lip A, which lip now extends nearly if not quite to the bottom of the finished and folded bag. This fold, like the rest, is fixed by any suitable pressure or other means.

As this specification refers exclusively to the bag itself and to the manner of foldingit from its pattern, I do not in any degree limit myself to any manner of making it. It may be made by hand, or by any suitable machinepreferably the latter, for reasons too apparent to explain.

By applying the paste 0 as indicated in the drawings each fold is fixed and the bag-bottom is closed in such a manner that pin-holes are avoided and the bag made perfectly tight.

When opened the bag constructed as above specified presents a square shape, as indicated in Fig. 11 of the drawings. This constitutes a package both efiective and attractive.

By cutting a continuous web or strip of paper transversely into blanks of the shape indicated by the pattern illustrated in Fig. 1 of the drawings, not only is all waste avoided,-

but longer and shorter lips are formed at the upper or open end of the bag-body, whereby the hand can readily be inserted and the bag thus readily and conveniently opened.

As shown in Fig. 2, the bag-pattern is susceptible of some slight. variation without any departure from my invention, and this variation simply consists in making the slantii'lg portions B B somewhat longer than shown in Fig. l of the drawings. WVhen thus formed the subsequent folds are made in the identical manner already specified, and the resulting bag for all practical purposes would be as good as that made from the pattern illustrated in Fig. 1; and as my manner of folding the pattern, rather than the pattern itself, constitutes the principal feature of my in vention, said pattern may be slightly varied from its exact shape as illustrated in the drawings without departing from my invention, so long as it can be folded in the manner specified to form substantially such a bag as described.

1 have described the shorter lip A as drawn back upon the seamless side of the bag-body to form the first of the bottom folds. It is evident, however, that if the blank is cut from the continuous tube with the seam side uppermost the shorter lip A would be found upon that side, and would in that case be turned back upon the seam side of the bag-body; and this might be done without any departure from myinvention, as, whileI prefer that the shorter lip A should be turned back upon the seamless side of the bag-body, I do not limit myself to that specific method of construction.

WVh at I claim is- 1. The following-described manner of foldin g a paper-bag pattern, consisting in forming the paper into a fiat tube having side folds or plica-tions (see Fig. 12) with the lower end of said tube constructed to have a long lower side and a short upper side, A, (see Figs. 3 and 4,) then drawing back upon the face of the bag-body the said short side A, (see Fig. 5,) then folding upon itself the long side, and,

finally, folding back the short side A over the folded long side, substantially as and for the purpose shown.

2. The process herein described of constructing a paper bag, consisting of the following steps: first, forming a tube with side folds or plications; second, cutting the tube in such a manner as to leave one side longer than the other; third, doubling the shorter side back upon the body of the bag; fourth, folding back the longer side of the tube upon the shorter, making the fold on a line with the terminus of the shorter side, then folding the short side back over the last-described fold, substantially as and for the purpose shown.

In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.
